# Description

Cluster workflow did not work with the different profiles and introduced
names. This PR fixes the workflow and in addition, introduces additional
checks that the profile can be selected. In detail:

- checks whether a profile can be selected depending on whether a
`.env.$container_profile` exists
- allows for `job` to have multiple arguments, also without a profile,
for all other options, the second argument has to be the profile
- check if a docker image exists before building the singularity image
- check if the path for the singularity image exists on the cluster,
otherwise create it
- check if the path for orbit exists on the cluster, otherwise create it
